Electronic device with conductive resilient sheet

Abstract

An electronic device includes a supporting member, a circuit board fixed to the supporting member, a bottom cover assembled with the supporting member, and at least one conductive resilient sheet fixed on the circuit board. The conductive resilient sheet includes a fixing portion fixed on the circuit board and a conductive portion. The conductive portion defines a first elastic sheet and a second elastic sheet. The bottom cover is fixed between the first elastic sheet resisting the outer side of the bottom cover and the second elastic sheet resisting the inner side of the bottom cover.

What is claimed is: 
     
       1. An electronic device, comprising:
 a supporting member; 
 a circuit board fixed on the supporting member; 
 a bottom cover assembled with the supporting member; and 
 at least one conductive resilient sheet comprising a fixing portion fixed on the circuit board and a conductive portion, wherein the conductive portion comprises a first elastic sheet and a second elastic sheet, and the bottom cover is fixed between the first elastic sheet resisting an outer surface of the bottom cover and the second elastic sheet resisting an inner surface of the bottom cover opposite to the outer surface of the bottom cover; 
 wherein at least one fixing hole is defined in the fixing portion, and the conductive resilient sheet is fixed on the circuit board by a fastener threaded through a corresponding at least one fixing hole. 
 
     
     
       2. The electronic device of  claim 1 , wherein the conductive portion further comprises a first through hole and a second through hole arranged apart and adjacent to an edge thereof, the first elastic sheet extends out from an inner side wall of the first through hole apart from the connecting portion and the second elastic sheet extends out from an inner side wall of the second through hole adjacent to the connecting portion. 
     
     
       3. The electronic device of  claim 1 , wherein the conductive resilient sheet further comprises a U-shaped connecting portion, the conductive portion extends from an end of the U-shaped connecting portion along a same plane, and the fixing portion extends from another end of the U-shaped connecting portion and bends outwardly and substantially perpendicularly to the conductive portion. 
     
     
       4. The electronic device of  claim 1 , wherein the supporting member comprises a base portion and four side walls extending upward from four edges of the base portion to cooperatively define a cavity to receive the circuit board. 
     
     
       5. The electronic device of  claim 4 , wherein two opposite side walls of the four side walls each comprises an engaging portion extending out from a top end thereof. 
     
     
       6. The electronic device of  claim 5 , wherein the bottom cover comprises a bottom plate, a first side frame, and a second side frame, and the first and second side frames extend upwardly from two opposite edges of the bottom plate. 
     
     
       7. The electronic device of  claim 6 , wherein each of the first and second side frames forms a latching hook corresponding to the latching holes of the two engaging portions, and each of the latching hooks is formed at the end of each of the side frames adjacent to the supporting member. 
     
     
       8. The electronic device of  claim 7 , wherein each of the first and second side frames defines a positioning hole corresponding to one locking hole adjacent to and apart from the latching hook. 
     
     
       9. An electronic device, comprising:
 a supporting member; 
 a bottom cover assembled with the supporting member; and 
 at least one conductive resilient sheet fixed on the supporting member, wherein the conductive resilient sheet comprises a fixing portion and a conductive portion comprising a first elastic sheet and a second elastic sheet, and the bottom cover is fixed between the first elastic sheet and the second elastic sheet, with the first elastic sheet resisting an inner surface of the bottom cover and the second elastic sheet resisting an outer surface of the bottom cover opposite to the outer surface of the bottom cover; 
 wherein at least one fixing hole is defined in the fixing portion, and the conductive resilient sheet is fixed on the supporting member by a fastener threaded through a corresponding at least one fixing hole.
